1.Why is reactive power compensation necessary? Reactive power is by no means useless power. In AC power supply systems, inductors and capacitors serve as essential loads. Ferromagnetic loads—such as electric motors and transformers—cannot function without inductive reactive power for excitation; meanwhile, long-distance transmission lines possess inherent capacitive characteristics, effectively a...

With the advancement of industrial automation technology, variable frequency drives (VFDs) are becoming increasingly widespread, garnering growing acclaim for their excellent speed-regulation capabilities and significant energy-saving effects. However, the harmonics generated during their operation pose an increasingly serious threat to the power grid; consequently, the need to suppress harmonic i...

In modern industrial power systems and commercial power distribution networks, dynamic load fluctuations, inductive equipment operation, and unbalanced three-phase currents often lead to low power factor, grid voltage fluctuation, reactive power loss, and harmonic pollution. These power quality problems not only increase electricity consumption and operating costs but also cause equipment overheat...
